A Prime Line® Exclusive!** Polyurethane stress cloud holds cell phones, paper clips and other desk items. Stress relievers are not intended to be children’s or pet’s toys. Our stress relievers are all made by hand; no two balls are exactly the same. It is impossible to guarantee a consistent, uniform imprint. Broad imprint areas are subject to breaking up, and the imprint may not be solid. We cannot guarantee PMS color matches on stress relievers. White stress relievers may discolor over time.
